Sooo, if FreeType is in C, and I am writing a binding... And there is an 
enum in the headers, which is refered to by the name of the enumeration...

I should take this...

/* C Code */
typedef enum FT_Glyph_Format_
{
	FT_GLYPH_FORMAT_NONE = 0,
	FT_GLYPH_FORMAT_COMPOSITE = 1668246896,
	FT_GLYPH_FORMAT_BITMAP = 1651078259,
	FT_GLYPH_FORMAT_OUTLINE = 1869968492,
	FT_GLYPH_FORMAT_PLOTTER = 1886154612
} FT_Glyph_Format;
/* */

and write this?

/* D Code */
alias int FT_Glyph_Format;
const int FT_GLYPH_FORMAT_NONE = 0;
const int FT_GLYPH_FORMAT_COMPOSITE = 1668246896;
const int FT_GLYPH_FORMAT_BITMAP = 1651078259;
const int FT_GLYPH_FORMAT_OUTLINE = 1869968492;
const int FT_GLYPH_FORMAT_PLOTTER = 1886154612;
/* */

The reason I am asking, is because I am getting an error that the 
FT_Glyph_Format is invalid, which to me hints wrong data type, but I 
have tried everything I feel like...

How big is a C enumeration in D? Am I doing this all wrong? ANY Help 
would be really great!

I would personally just do this:

enum FT_Glyph_Format
{
     FT_GLYPH_FORMAT_NONE = 0,
     FT_GLYPH_FORMAT_COMPOSITE = 1668246896,
     FT_GLYPH_FORMAT_BITMAP = 1651078259,
     FT_GLYPH_FORMAT_OUTLINE = 1869968492,
     FT_GLYPH_FORMAT_PLOTTER = 1886154612
}

But you could do this:

alias int FT_Glyph_Format;
const FT_Glyph_Format FT_GLYPH_FORMAT_NONE = 0;
const FT_Glyph_Format FT_GLYPH_FORMAT_COMPOSITE = 1668246896;
const FT_Glyph_Format FT_GLYPH_FORMAT_BITMAP = 1651078259;
const FT_Glyph_Format FT_GLYPH_FORMAT_OUTLINE = 1869968492;
const FT_Glyph_Format FT_GLYPH_FORMAT_PLOTTER = 1886154612;

An enum will be, afaik, an int by default.

How about this?

     enum FT_Glyph_Format {
         NONE      = 0,
         COMPOSITE = 1668246896,
         BITMAP    = 1651078259,
         OUTLINE   = 1869968492,
         PLOTTER   = 1886154612
     }

No point forcing yourself to write such redundancies as 
FT_Glyph_Format.FT_GLYPH_FORMAT_COMPOSITE all the time.  This way, the 
final underscore effectively turns into a dot.  This is how, in SDWF, I 
create enums from Windows API constants.
